I rarely work from sketches, preferring to go straight in with the tape on to the glass. As well as this though, I am incessantly drawing in sketchbooks, its just that these rarely become tape drawings.
The below images are an example of when this isn’t the case. The top images is one of my sketchbook drawings (most of which are never seen or exhibited), and the bottom is electrical tape on glass. I liked the sketch so much that I decided to replicate it with tape. The tape drawing is much larger than the sketch, and is a mirror image as when I do a tape drawing I tape on to the glass and then set that in resin, then I flip it and frame it so you’re essentially looking through the glass at the tape.
